Abstract
Postgraduate enrollment expansion policies in China have formed a development system of postgraduate education with an expansion of scale and increase of categories. Taking the institutional equilibrium theory as the prerequisite of assumption, this study evaluates 30 postgraduate enrollment expansion policies using the fuzzy set qualitative comparative analysis method (fsQCA method) and explores the matching degree between policy changing path and social development. It is found that path dependence is the main cause and trend of progressive policy change, the construction of the national strategy determines the direction and content of policy change, and the environment induces the abrupt logic and gives early warning to policy change. Therefore, the postgraduate enrollment expansion policy system respects the law of education itself, has contingency and flexibility, adjusts the training structure, and improves the competence of highly specialized talents to serve society. However, it is still necessary to closely follow the social demand to clarify the dialectical relationship between the scale and structure of postgraduate enrollment and highlight the strategic advantages of the government's decision.
